Zetasizer Nano ZS Size Analyzer, Malvern Panalytical (CAT#: STEM-LE-0335-LC)

The Zetasizer Nano ZS is a high performance two angle particle and molecular size analyzer which an enhance detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration through dynamic light scattering with 'NIBS' optics. The ZSP also comes with a zeta potential analyzer for for particles, molecules and surfaces with electrophoretic light scattering, and a molecular weight analyzer with static light scattering.
